    Angry unable to read ECU - Unlocker x36 exceec number of attempts

    Hi,

    I'm looking to read ecu from 2007 Z06 but error "Unlocker x36 exceec number of attempts" fail the reading.

    I've try to other 2 C6 where I make a custom tune and all work perfectly !!!
    Charged battery , try to read again with 12,4 volt, FAILED.

    Updated the VCM to the never 3.6.26 version, try again to read, FAILED.

    What it's the pronlem ?

    Chris

    I think that means the pcm might be tuner locked with some other software.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    That was just my best guess at the problem after seeing other people show the same issue.

    If it was locked you'd have to unlock it with whatever tuning software did it.
